certain new and useful Improvements in Portable` Houses, of which the followingl is a specification.

My said invention relates to improvements in port- The objects of the invention are the provision of a house of this character, made of sections by which the house itself may be extended, or decreased, quickly and with facility; to provide interchangeable sections that may be used in different portions of the house,

to provide overlapping cross bars on -the sections to guide and hold the same to desired position when being l sectional view of a house embodying the features of my invention. 2 is a view in elevation, partly broken away, showing the front outside, and the rear inside of the house illustrated in Fig. l. Figs. 3, 4, 5, and 6 illustrate different `shapes and sizes of houses which may be constructed by the sections` embodied in the invention, Fig. (j illustrating a double house. Figs. 7 and 8 are diagrammatic representations of other forms which may be built according to this invention. Fig. 9 illustrates in horizontal'section, the construction of one of the corners of the house. Fig. 10-is a section on line 101O Fig. 2. Fig. l1. is a horizontal section of the outer corner taken atthe line X-Z Fig. 7, and Fig. 12 is a similar section of the inner corner in the salue figure. Fig. 13 is an enlarged View of the upper left hand corner construction in Fig, 1. Fig. 14 is a vertical section at the apex A of the roof in the double house shown in Fig.,6. Fig. 15 is a view on the joint line 'i4-'1 4 in Fig. 6. Fig. 16 is a vertical section illustrating the supportfor the double sloped roof of Fi'g. 6.

' Fig. 17 is a, section of a roof joint, at B, in Fig. 2, and

Fig. 18 is a modified construction of roof jeintwherein tar paper is used. u,

As illustrated in Figs. 3 to 8 inclusive, the house may be made up into a variety of different forms and sizes, but the sections are duplicated, and interchangeable. The foundation or support for the house consists of sec- 'tions of timber,as 1, l, of suitable sizes, rabbeted at the end as illustrated, and preferably detachably connected by the hooks 2 and eyes 3. Upon the timber sections l the superstructure is erected, and there held in position by stringers 4, secured on top of the foundation. Against these stringere the bottom or lower side therein.

As illustrated, for example, in Fig. 5, when it is de-l sired to extend the front of the house, a blank section 9 lmay be employed, eitherl between a door section and a window section, or at the left of a door section (Fig. 5)

or in general, on either side of any other section. The side sections 10, are preferably Vformed to slope at the top with the gable roof portion 11, and in some instances it is desirable to have a section 10 provided with a window. At the rear side of the house the sections 12 are madejof the saine width as the corresponding iront sections 5 and are similarly constructed. All the sections are made up of tongue and groove boards, the joints being illustrated atr14, and cach section is provided with two or more battans l5, 15, to which the boards are secured, as by nails or screws.

The floor portion 16 rests upon Ithe stringers 4 and the various side, rear, and front sections, are detachably secured together by hooks 17 and eyes 18, as is also the roof portion secured to the sides.

As illustrated the battens are arranged on the sec- The roof portion at front and rear is provided with4 stringers or beams 19, 20,` which, form'between them a space for the reception of the front sections 5 and rear sections l2, respectively; the roof portion being slipped down over the top of the vertical sections and holding them in place. The two inside stringers are oreshortened attheir ends to allow the roof to overlap the side walls of the house.

In Fig. 9 a common corner of the building is illustrated, and in Fig. 10, the joint between two alined sections is shown. In these joints, as in other joints to be described the feather 21 is inserted to make the joint weather tight. `The corner construction of Fig. 9 shows a front section 5 and a side section l0, the permanent joint at the corner being a rabbet joint.

Fig. 1l. indicates a double feather joint construction at the outside corner of a house as illustrated in Fig.

7, and Fig. 12 shows asimilar double feather-joint at the inner corner Z of Fig. 7. In Fig. 12 an upright post 22 is provided with two feathers 21, 21, and the adjoining sections are grooved to seat over these feathers.

At the corner joints I preferably secure the strengthening blocks 23, 24, to secure rigidity and stability, said blocks being securely fastened tothe adjoining comer sections, and overlapping the4 adjoining wall section like the overlapping battens in other joints.

The double house illustrated in Fig. 6 requires but slight modification in itscorner roof construction from single construction shown in Fig. 13.

I have described hooks and eyes as the means'for dei tachably securing the sections together, but for large houses, and to secure rigidity in some places, I employ bolts instead of hooks and eye's. -For example, in Fig.

15, in securing the iront sections of a double house,

Where an upright post 25 is interposed betweenthe adjoining sections, I provide each section with an angle iron 26, which may be seemed to a strip or batten 15, as illustrated, and these angle irons haye holesin them through which thebolt 26- is passed and' secured by a nut as 27. As many of these bolts may beused asis desirable, and' it will be obvious Athat a secure and tight joint may be formed by this construction. Preferably a strip 28 is secured to the post 25 to cover the joints between the post and the sections, and give a finish to the iront appearance ofthe house. If desired, a girder or beam 29, havingconnected thereto short connecting pieces 30, and roof strips or gil-ders 31, forming a frame? Work for the support of the roof, may be used, and thev pieces connected by plates as 32.

To insure a Water tight joint and protection from the weather, a tin( covering may be provided for the house as shown at 33, in Fig. 17, or tar paper 34, may

be used as illustrated in Fig. 18.

by omitting one or more sections, various sizes and shapes may be produced. The sections are interchangeable, and the detachable connections 4insure a rapid erection and d ismemberment of the house.

Having thus Yfully described my invention, what I.

claim as new and desire to secure by Letters Patent is:

1. sectional house having feather joints between the sections, hooks and eyes on the sections for detachable connection therebetween, vbattens secured to each section adapted to overlap the adjoining sections, triangular corner blocks a .ioor, a detachable roof, and hooks and eyes for securing the roof to the house sections.

2. The combination in a sectional house of rabbeted stringers forming the foundation, n oor, sections provided with doors and windows, hooks and eyes for securing the sections together, feather joints between the adjoining sections, and overlapping batte-ns carried by the sections for guiding the sections in position and vholding the same.

3. The combination in a sectional housel of rabbeted stringers forming the foundation, hooks and eyes for connecting said stringers,l a floor, sections provided with doors and windows, battens on thevsections overlappingI each other and forming guides, hooks andeyes' for securing the sections together, a roof, and'books and eyes'for securing the roof to the sections.

In testimony whereof I aiiix my signature in presence of twowitnesses.
